Using different profiles (.kshrc_xxx) in ksh

In bash you can load a different profile by using the --rcfile option, is there such an option in ksh? Or perhaps a workaround...

I know you can invoke the shell without the .kshrc profile using the +E option, however I wanting to use another .kshrc file (i.e. .kshrc_xxx) as an option instead of the default as needed.
