Intensity and phase images are lost when using creat stack

Induvidal pairs by back-geocode(from topsar) and debust generate 27 file stack . Next step, i want to gather 27 pairs to a stack by create stack tool. Create stack make the stack without intensity band, which can’t use for StaMPS in step2.
the question is “How to gather 27 coregister pair to once stack without lost intensity band or phase band?” .

the intensity and phase bands are just virtually stored. As long i and q are in the product, you can either re-create them (Raster > Data conversion > Complex to intensity / phase) or simply leave it because SNAP knows how to treat them.

thank you.that like your reply Intensity or phase layer not affect to the product.
