you can use the snap2stamps package: Snap2stamps package: a free tool to automate the SNAP-StaMPS Workflow
The first three scripts
- slaves_prep
- splitting_slaves
- coreg_ifg_topsar
will automate what you want to do, at least until the deburst and unwrapping steps, which have to follow. But the mentioned ones are surely the ones which cause the most work and you should be able to do the rest in comparably short time then.
