how can i have more than 3 necessary branches in fork element in Integration process in PI 7.1?

Hi Everyone,

how can i have more than 3 necessary branches in fork element in Integration process in PI 7.1?

by adding a block element I can have 3 necessary branches... but I need 7 necessary branches.... kindly explain please... my scenario has 7 different senders and one receiver. I need to combine messages from all the 7 senders to the receiver.

Thanks,

Nirmal.
