Bc2000 (for the BCF2000 & BCR2000)

Hello, 
How would I assign a group of 8 encoders to one push encoder?
What I am after is to assign 8 midi CC functions to encoders #1-#8, that would be assigned to push encoder #1 and be activated when I push on it.
then assign the same 8 encoders (with different functions)to push button encoder #2.
 Something like what the 4 encoder groups do, each one is activated with a simple push on of 4 buttons, giving you 4 different groups.
So 8 top encoders would each 'activate' 8 groups of functions.. 

I need it, because I have this virtual instrument that has 6 tracks =6 pages with same 8 functions...6x choose sample, 6x sample start, etc.
even though they are same functions, they have different midi number. 

TIA
PS If I did not explained  myself clearly, i'll try again
