Cross Reference Plan - Using a column which use already a cross reference plan

Summary:

I need to create historic N-1 and Historic N-2 and Historic N-3.

Content (required):

I have used in a "user-defined columns" the numeric column 19 with a "cross reference plan" to have Historic N-1 : "Individual Increase N-1".

I would like to use in another numeric column the cross reference plan, with the numeric column 19, in order to have N-2.

But the field is not avaible in the search "column to cross reference".

Is it possible?

Or do I have to create a Fast Formula?
