Hashcat Is it possible create custom algorithm

[krbsns]

I have a hash whose algorithm I know. I need to solve it. But what would you suggest that this algorithm does not appear in options?
sample hash:salt 5322640b90f418ae6ede3a6b88873ab7:y880wm7lyd hash algorithm @md5(md5($password) . $salt . md5($password))
If there is no defined algorithm, is it possible to create a custom algorithm rule myself?
I can try passwordpro , john and hashcat..

John:
--format=dynamic=md5(md5($pass).$salt.md5($pass))

5322640b90f418ae6ede3a6b88873ab7:y880wm7lyd:123456

 

[krbsns]

John:
--format=dynamic=md5(md5($pass).$salt.md5($pass))

5322640b90f418ae6ede3a6b88873ab7:y880wm7lyd:123456

it gives this error : No password hashes loaded (see FAQ)

My file format is hash:salt like 5322640b90f418ae6ede3a6b88873ab7:y880wm7lyd
Is there any other arguments I should add?

try to use $ as hash salt seperator
