Sorry - I don't quite understand your first question. The answer to the second is "no" but it may be possible to write a routine using API to do it.
There is a macro listed in this thread that will accomplish this.
Also one that we use listed below. Can't remember where it came from so I can't attribute it properly.
It will drop a pdf and dxf into a folder named after the first 3 digits of the file with the revision (of the slddrw) stuck on the end of the filename. So you should be able to customise it to your filename settings by adjusting that ODrivePath line below and filename line too if you use a different string length for your part numbers.
Set swApp = Application.SldWorks
Set swModel = swApp.ActiveDoc
' Check to see if a document is loaded.
If swModel Is Nothing Then
swApp.SendMsgToUser ("Open a drawing first")
' If no model currently loaded, then exit
' Determine the document type. If the document is not a drawing then send a message to the user.
If (swModel.GetType <> swDocDRAWING) Then
swApp.SendMsgToUser ("To be used used for drawings only")
' If document is not a drawing, then exit
Fileprop = swModel.CustomInfo("Revision") 'Change the custom property name here
'Filepath = Left(swModel.GetPathName, InStrRev(swModel.GetPathName, "\"))
FileName = Left(swModel.GetTitle, 8)
ODrivePath = "O:\issued\" + Left(swModel.GetTitle, 3) + "\"
swModel.SaveAs (ODrivePath + FileName + "-" + Fileprop + ".PDF")
swModel.SaveAs (ODrivePath + FileName + "-" + Fileprop + ".DXF")
