Creating toolbar text inputs to auto populate fields on feature creation

Hi,

I want to setup a toolbar that users can input the common details about a particular edit session, such as install date, as built document reference, etc etc

And then have these values auto populate the corresponding fields across the range of features created.

This seems like the place to start http://help.arcgis.com/en/sdk/10.0/a...00000391000000 (Building editor extensions using add-ins)

But I get the impression that simple text inputs are difficult to put in the toolbars?

I've not worked with ArcObjects before but if someone could outline if it's A. possible and B. a general approach then it would be a great start.

Or is this something that could potentially be acheived with python add-ins.

Thanks for your time!
Steven
