It would be great to have a native solution to this problem.
Let’s say I used the SendGrid block to email all Users in a certain grid view.
Now I want to document that the email was sent out to them in a separate Emails table.
Currently I have to manually add each emailed user to a linked Users field.
Instead, it would be great to have a method of automatically adding multiple linked records to that linked cell.
Here are two approaches to this:
1. Add a new paste option
If someone has a linked cell selected:

And then pastes a few records, I should get the option to add them to that cell (as long as they include a valid primary field that matches existing records).

For what it’s worth, all you need to do for this to work is replace newlines with commas
2. Bulk add everyone from a given view
Similar to how SendGrid can automatically send emails to everyone in a filtered view, allow the addition of multiple records at once.

Right now, adding 20 people to a sent email is really complicated and frustrating.
Either of these approaches (or many others you might come up with) would solve that.
