On-the-Fly Field for Inventory Label Printing

Is there a way we can add an "on-the-fly" text field that will show up on printed labels through Inventory Label Printing? Our previous ERP system had a textbox on the print screen that allowed the user to type in a custom remark that then printed out on each inventory label. This was really convenient for us and I'm not seeing a way for us to do this in Sage. Any feedback or creative solutions would be appreciated.

Thank You!
