split-text extension splits into unflowed-text

This cool extension takes your text-object and creates other objects each containing a letter or line.

The only problem is that the resulting objects are different, as text can't be flowed. I failed to "reconfigure" them with Alt-W, as "Flow into Frame" doesn't do anything unless I provide a frame to wrap to accordingly, and because I adjust text "frame" in time it would be overkill to keep reframing.
