I have never tested that software.
But Construct can import strips yes. This has been supported since ages I believe. And I guess the software you are looking at can export strips. (many frames in a single picture, like a grid sort of)
Edit: I looked at their website, it says the software can export PNG sequences. Which I guess can be imported fine in Construct editor. (right click>Import frames)
The software is free to try, so just try it and see :)
