Hi @SamuelSh3,
Not to my knowledge, natively.
Instead, one approach is to consider (and perhaps suffix) the text field as an "Override", and create calculated parameter (perhaps with the original parameter's name) with a formula similar to this:
IF(ISBLANK({DE:Text Override},"Default Text",{DE:Text Override})
Technically, the former need only be presented when input/edits are appropriate, and (more often) the latter then used on reports, views, etc.
Mileage may vary. Some training required.
Regards,
Doug
