Please use the addon comments and ask the author, or write a PM to him/her instead of starting forum threads.
Each addon got it's own section for exactly that purpose.
Or use the feature request panel of the addon dev if he/she had enabled it. It would be visible below the "Download" section (not visible so not enabled for that addon dev).
If you would read the comments you would see that someone "Dose" already explained how to add the companions there.
There also exist several other addons about companions (if that is what you mean by allies?).
