Hashcat GUI Hash Type

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?
