Thank you for presenting your use case! I will create a feature request to implement the ability to set fixed dimensions for a shape and also to allow the option to automatically group shapes with corresponding text. If you have any further information you want to add or any further questions, please don’t hesitate to contact us directly via the Support Centre form at help.avenza.com > Contact Us (Get Help).
Please let me know if you have any questions!
All the best,
Avenza Systems Inc.
