Different offer extension letter for contingent worker

Summary:

In ORC, as we know if we enable 'Bypass Offer' option then it gets applicable to all type of candidates which is not our business ask. So to get through it, we have created separate offer template for 'Contingent workers' as well for 'Interns' but only problem we facing and need your help to sort out is -

Do we have any possibility to control or amend the 'Extend Job Offer' notification. Can we create separate version of this standard notification which is under alert composer? We want to have separate notification of 'Extend job offer' for external/internal, contingent worker, intern candidates.
