Matt,
In Workforce you will be able to easily jump out to Collector if you have it installed on the device. This might not be in the initial Beta releases but certainly in our first Non-beta release we will have logical integration points setup Between Workforce and a number of our apps (Collector, Navigator, Survey123 etc...).
We are still trying to get the story ironed out but we are thinking that when you setup a project you will be able to configure specific assignments to link to specific Webmaps which can be edited in Collector. This would provide a very streamlined experience for your field workers allowing them to go straight to collector for editing and back to Workforce.
This story should get more fleshed out as the beta release evolves and be fully implemented for our first release after beta.
