Hi @fedoras,

There is a database preference where you can configure whether or not you can add children to synonyms:

> [@Enable creating children for synonymized nodes](https://speciforum.org/t/enable-creating-children-for-synonymized-nodes/987):
>
> Starting in Specify 7.8.4, you can enable a secret preference that allows synonymizing a node that has children and adding children to a synonymized node. This has been requested by many members of the consortium, including @Ben, @Plarson, @Schuchert , and @HeatherC. You can enable this functionality by adding this line to your Remote User Prefs file in the [App Resources](https://speciforum.org/t/app-resources-in-specify-7/582) viewer. If you have any questions or need some help, please feel free to send us a message! Allow Adding Children to Synony…

Can you try this and let me know if your issue is solved? Thank you!
