Start a sequence on behalf of another HS user

Not having this feature gates features that make it really hard for small companies to adopt and use hubspot. This can be solved, but only at the Hubspot Enterprise tier, which includes a bunch of stuff that a small company doesn’t actually need.
Here is a reasonable workflow example:
We go to an event. We connected with 200 people that we told we would follow up with directly. We upload the names into Hubspot and now have a list. We want to use a sequence to assign someone to
Step 1. Call them
Step 2. Send a manual follow-up email
Step 3. Send an auto email bump
Step 4. A task to disposition them.
We want these to automatically land in the task queue of one of 3 sales reps. Right now, we need each sales rep to manually go find the leads and sequence them, RATHER than having the ability to sequence all the leads based on ownership from a single list.
This isn’t enterprise-level functionality. This is small business stuff.
