Move or copy a Part inside project?

Please help me, I am lost. OT mk2

Parts store machines, settings, FX. Patterns – trigs, locks.
How can I change the corresponding part for the pattern in different bank?
For example, I want to have the same pattern (A1 and B1), but linked to different Parts.

I copy part A into part B.
Then I copy Pattern A1 into Pattern B1

But, B1 will be tied to Part A (since A1 was tied to Part1), so when I will chose B1 it will play mess (not exectly what A1 should play)
So I want A1 be linked to Part1 and B1 to Part2 and sound exactly the same, so I can change from there B2.
Please hep
