I have a table where I want all new entries (rows) to have a default value for a single select column. Is that possible?
Unfortunately, there’s not. Single Select is one of the many fields that currently do not have a default value option where one would be very nice. I believe there’s a #feature-requests addressing this out there already. You might consider looking it up and adding your support there.
This is unfortunately the case - there is a possible solution (work around really) available to you by using Integromat or Zapier. Using either, you could watch for new records where this field is blank and fill it in. The only downside is that this wouldn’t be instant of course.
Hope this helps?
