variable sweep in ADEXL

I have two variables defined in ADEXL.

I want to sweep variable A, with Four values, 1,2,3,4.

Then I want to make variable B sweep dependent on A.

For instance, when A is 1, then B sweeps from 1 to 3. When A is 2, B sweeps from 3 to 5. When A is 3, then B sweeps to 6 to 9.

How can I achieve this? is there a way to use some logic expression in the variable definition?

Thanks!
