@Darren_Murphy Do you mean the workaround is something similar to this? > [@Using Call API and Glide API to add rows to related tables. Also...JSON Object!](https://community.glideapps.com/t/using-call-api-and-glide-api-to-add-rows-to-related-tables-also-json-object/70860): > > I wanted to show how you can use our new JSON columns to allow you use Call API into the Glide API. This allows you to create multiple rows in a different table and related them to the main table. Marco created a great [video](https://www.youtube.com/watch?v=b7_k3_brusQ&t=6s) showing how this was done with an older method (before we had all the great new JSON columns) that used a combination of template fields but you can do this all with just a JSON Object column now. Here is a [Loom video](https://www.loom.com/share/041b3cf99dec42c1a4d25af8c7aee38f) to explain. If I missed explaining anything feel free… This would also use Lookup from Glide Big table (In My case) when it tries doing the lookup from the Previous table. As I need to fetch JSON from previous table. Still gives the warning of more than 100 rows thing.
