Yes, within a Merge turnsheet, you can use the Automate feature to create turnsheet columns that automatically fill and update themselves based on other inputs. To automate a column, select Edit Column for any Text column in your turnsheet and press the Automate toggle. From here you can use the simple if-then logic builder to start automating your work.

If you want to reuse the same automations in your next matter or share them with your team, save your matter as a template, so you don't have to build them from scratch next time.
