sql server - SSRS: Report label position dynamic -

i have report displays customer address in multiple labels.

my customers use windowed envelopes mailing. need address labels position configurable.

something like, i'll have database table stores top/left position of each label per customer. based on table, need position address labels on report.

i thought, doable expressions, location property doesn't provides ability set expression , make label's top , left dynamic.

anybody, ideas, on how achieve this?

as mentioned, cannot set expression location property. want before seems there no solution work.
