[Spce-user] [EXTERNAL] Rewrite Rule Set number manipulation question

[Marco Capetta]

Hi Edo,

Rewriting Rules are the thing to use in cases like this one.
You can also use some online tools like https://regex101.com/ to tests your
regex.

I think in your case you need something like this:
match: ^99888([0-9]+)$
replace: \1

Cheers
Marco
