certificate file name at renewal

[exenza]

Hello,
I'm sharing NPM docker volume with AdGuard so that I can use the NPM certificate with it.

The issue is that when auto-renewed the filename of the certificate changes from:
/opt/ssl/archive/npm-1/fullchain1.pem and /opt/ssl/archive/npm-1/privkey1.pem
to:
/opt/ssl/archive/npm-1/fullchain2.pem and /opt/ssl/archive/npm-1/privkey2.pem

which breaks AdGuard SSL until I manually change that in AdGuard.

Would it be possible to change this behaviour allowing users to discard old certificate and use same name at renewal?
