Urgent: Is EAD AP portable?

[godisgood]

I am ready to file a new 485 myself. I already have EAD/AP approved from my employer's 485. Can I reuse the approved EAD/AP with my new 485?

Reason to file new 485: My NIW got approved. It is much safe to use my own I140 instead of concurrent-filing-but-not-yet-approved I140 with substitution LC.

EAD and AP are valid until expired or expressly revoked by INS.
