Hope InterpcrvOnSrf is connected to the history, and during secondary editing, you can edit control points again, add or delete them, and move them.
This command supports recording history. Except for not being able to remove points, eveything else can be achieved.

Is there any way to add editable points during secondary editing
only through the flow commands for instance FlowAlongSrf. what kind of surface do you have?
a sphere is a tricky kind of extreme case because you can not unroll it easily, so i sliced it into to halves and used Smash to unroll it. after that you draw your curve on the flattened surface with history enabled and use FlowAlongSrf with options Autoadjust and preserve structure maybe. then you can use InsertEditPoint to add points and or change the exisiting curve to your likings, it will update instantly.
The feature request is on the list as RH-95581 .
history does not get to much love and sadly is very limited.
another limited workaround:
…might be to draw an initial _interPCrv with _PersistentOnSrf (snapping)
then use _pull with copy option and history
put the pulled curve on a separate layer and look this layer.
editing will be a bit tenacious / bulky - if the reference curve is of _pull back the edit points (not the curve as this will break history - at least in rh 8)
it s a pity ApplyCrv does not support history.
it should be straight forward to set up a small sketch with grasshopper.
do you have a special usecase / sample ?
kind regards - tom
