Possible to use automation to create a link between two records without deleting any existing links?

I have a table for “teams” and a table for “tournaments”. There is a linked field between the two.

I want to create a button in a Glide app for my end user that allows them to “Register” their team for a specific tournament, but I can’t find a straightforward way to update a linked field to add a linked record that doesn’t clear out existing linked fields.

Example: When the administrator for the red team clicks a button on the tournament page, this tournament is added to their team’s list of tournaments in the “tournament” field and vice versa.

Because a team can register for multiple tournaments and tournaments can have multiple teams, I want to update this linked field without clearing out existing records in these fields.

Is this possible?

Yeap, you should be able to use the data from the record itself

Assuming your automation is triggering on the record that you want to update, it’d look something like this:

And here’s a link to the base so you can check out the input tokens yourself

@49erAllie Adam’s automation above will not work if the new entry is the very first entry in your linked record field.

You have to swap the 2 items in the linked record field: the new entry has to come first, and then type a comma, and then add the linked record field’s values afterwards.
