How to stop an IPO set to cyclic

Is it possible to stop an ipo, set to cyclic, after lets say 50 frames to be able to animate it myself again. Ctrl-Shift-A isnt working as in “Make Duplis real”

Thanx, Twan

i think it’s not possible to do it automatically.
Manually, this is how it worked for me:
-define the keys that you want to be cyclic
-select them all and Shift+D to duplicate them
-move the duplicates along the time axis to create a cycle
-repeat steps 2 and 3 untill you want the cycle to end the you can modify the curve anyway you want
