I had a similar problem yesterday: I tried to have a jpg as a screen replacement, and, as you say, couldn't change the duration.
My workaround: Import the picture on the media page, put it in some timeline on edit page and drag it to the desired length, create a compound clip out of it and use that as the new picture on the fusion page out of the media bin.
Any other ways to get there are welcome.
Tech:
Win 10 pro, Ryzen 9 5900X, 128 GB, M.2 for media
RTX 3080 ti, Intensity Pro, DVR Studio + Fusion 19.x, Desktop Video 12.x
