Bruteforce RAR3 with repeated password

[RARcheologist]

I am trying to bruteforce a RAR3 file with a repeating password

Let's say the password is abc$1abc$1

I want to bruteforce the abc$1 part and duplicate it.

For a simple password like abc$1, this works:

hashcat.exe -m 12500 -a3 hash ?l?l?s?d

But what if I want to bruteforce using only duplicates of ?l?l?s?d, like aaa!1aaa!1 or zzz=0zzz=0, how do I do it?

I tried creating a duplicate.rule with just a d in it, but it won't allow me to use rules in brute force mode.

Any help is appreciated!
