Hashcat GUI Hash Type

[hidev2]

Hello, so I've downloaded HashcatGUI and oclHashcat but I'm having problems with the "Hash Type" section. I'm trying to find the hashes for IPB, smf and MyBB which are; md5(md5($salt).md5($pass)), sha1(strtolower($username).$pass) and md5(md5($salt).$pass). However in the hash type dropdown I'm not seeing these. 



Any way to custom add the hash types I require?
