Prostructures-Concrete Bar Marks

I am trying to create a Bar Bending Schedule from my Rebar Model.

Is there a way to adjust the Bar Marks for all bars before they get automatically assigned to a bar.

I'm am looking for have Bar Mark designations that helps differentiate Vertical and Horizontal bars in the Schedule.

Also other miscellaneous Rebar types (Stirrups, Tie Bars, Filler bars, Diagonal) for example.

Right now all my Bar Marks are the same. "4T1, 4T2" etc.

Also, in one model I can apply bar marks to straight bars and in another model I can not apply bar marks to straight bars. Not sure why this is and what setting controls this.

Any help or suggestions on these issues is appreciated.
