Simple 3000 question. Need help

How do I set the number of loops for a sequence?

Say I want to create a four bar loop? Or an 8 bar loop?

In the MPC2000XL you choose the number of loops in the main screen, but what about the MPC3000?

Don't tell me I can't............

Edit>add bars or copy bars, then set ther loop to bar field in the main screen to 1 or whatever.
