Hi,
Yes, you can paste comma-separated list of names, for example, and it will link to all of them. But it won't work as desired, if the primary field of employee table contains commas. Also, if the list contain errors and Airtable cannot find such employee, it will create new record(s) and link to them. So, before pasting take a look at the number of records in employee table and disable sorting.  

select operations, for example, and it adds everyone's name from that team to that field
I would do the opposite - add any person from operations, switch to employee table, filter to show operations only, find that person and field, linked to training and copy-paste this value to the whole column.


You could also do grouping/collapse all , to be able to quickly copy-paste values to some groups - only expanded group(s) will be affected when you paste to the whole column.

Try this extension.

LinkRecordHelper - Marketplace - Airtable

Also, you can generate a list of people from a group record using a formula and paste it in.

Thanks Alexey! For the recommendation for doing the opposite I'm not sure I understand what you mean. Would I add them first to the trainings table or the employee?

I really like this extension. Thanks Sho!
