Sounds like an enhancement request
As Troy said, time for an ER (or a plain old; Make it Functional).
However, from the never ending list, here is yet another "SolidWorkAround":
Using the HW, create one hole, then the other.
Add a hole callout (results in a single hole)
Select callout with RMB and choose Display Options, then, Define by geometry.

Thanks for the great workaround. I had no idea that command was there. It's the next best thing to a real Drill&Ream HW selection.......Bill
two things come to mind.
- omit the drill, from a drawing standpoint the final diameter is all that is required.
- use a counterbore, that's what it really is.
imho, this is almost like having dims for rough machining and fine machining, from a drawing standpoint, all that really matters is the final dimensions.
if you need to "tell" someone "how to make" the part usually the routing would detail the procedure.
Cbore would work but the hole callout would show a 180° drill angle which might be a little misleading. Eddie came up with the best answer for my needs, at least until there's a real Drill&Ream HW and callout.
And in most cases I'm not trying tell lead the machinist by the hand (I hate it when I'm the machinist and someone does that to me), I'm making sure we have a way to remove the dowel pin if necessary. A blind hole would work fine until you had to remove the pin.
I will agree, per ASME Y14.5M, manufacturing terms like; DRILL, REAM, BORE, etc., should not be used. However, in special circumstances, MFG DATA is allowed.
However, Bill's case where a pre-drill (or pilot) and then a ream, may actually be a requirement versus a mere pre-machining process. Such would be the case if the holes were defining the requirements for a Lee Plug, Lee Check Valve or other similar products. They require a hole with a loose tolerance followed by another hole with a standard 118° included angle. The secondary hole is typically 4 decimal places with a tolerance range in tenths (.1880/.1875). Lastly, in the case of holes for the above mentioned Lee products, the secondary hole operation is not a counter bore.
i forgot about the c'bore symbol which could undoubtedly lead to confusion.
I use the Legacy feature in HW and choose "Counterdrilled" option from the pull-down.
However, Hole Callout doesn't word it like I want and I edit the text as I place it.
