How do I combine different learned policies. For example: First Pick than Place

Hello :)
I am currently working on an adaptation of the factory paper. In it, it is described that different policies for picking an object and placing are “played” sequentially. How do I do that in Isaac Lab /Sim?
So for example I trained an policy for picking up an object. Than I want to manually move the object (via IK) to the target position and afterwards I use my trained place policy to place the object.
Thanks in advance :)
