Match number of items in each branch

Hi everyone,

I have two lists of curves A and B, both have the same number of branches, but list A have only one item per branch and list B can have one or two items. For each item in the list B I want to multiply the number of items in the list A, so at the end I will end up with the same number of elements in each lists.

e.g. (for branch 1 in list A I want to have two times the same curve, and the same for the branch 2 and so on )

List A (Data with 88 branches)

{0} N=1

{1} N=1

{2} N=1

{3} N=1...

List B (Data with 88 branches)

{0} N=1

{1} N=2

{2} N=2

{3} N=1...

NEW List A (Data with 88 branches)

{0} N=1

{1} N=2 

{2} N=2

{3} N=1...

Any suggestions about how to do this?

Thank you,

Martha
