Try saving your font / annotations to a new drafting standard (at the top of the document properties). This should keep all those settings together so you can recall them all at once, rather than setting each parameter every time.
Alternatively, you could save your settings to a drawing template, and just make sure to choose the appropriate template when you create your drawing.
Tools > Options > Document Properties > Annotations > Font
You can change these in your system options - under the document properties tab when you have a drawing open.
