Prevent rpm sign from prompting more than once

On RHEL 8, you can do an rpm --addsign or --resign and then enter your signing key password once and you're good to go to sign several more packages without having to enter it again.

Is there any way to get this same behavior working on RHEL 7? Currently if I try to sign more than one package, RHEL 7 prompts me every time for the password for each package.
