Hello,
The only way to handle pressed tubed in Advance Steel is to set a shrink value to them from their properties dialogue. This will not change anything in the model (the element will keep its initial size), the only place where you will see this difference will be in BoM extracts. Joints will still be created on the initial, not deformed shape of the pressed tube.
More details of how the shrink options works can be found in the following FAQ :
What is the shrink option used for?.

Dumitru Berteanu
