Is it advised to create multiple LUIS models using dispatch?

Question

Requirement: I need to enable bot to handle QnAs, talk to SharePoint list for dynamic form flows and return custom designed cards/actions, preconfigured troubleshooting services with common questions and integration of Service Now etc.

Question: Since the bot is doing more than one, should I consider designing individual LUIS models and use dispatcher service? or could I build it using multiple intends with single LUIS model?
