1 Line text box with scroll bars

[mdeyedoc]

I used several 2-line textboxes on my template in order to have scroll bars if the context was longer than usual. However the F9 autofill does NOT work with multi-line textboxes. I tried the custom text box but it acts like a 4 line textbox. I'm not even sure how they are different since you can resize either one. Anyway, it would be very helpful if we could get a custom sized text box (with scrollbars) that acted like a 1-line text box as far as F9s go.
