Is it possible to achieve a single curved corner in a table in EngageOne Designer

Product Feature: Document Editor
 
It is not possible to setup a table where only one of the four corners of the table is curved.

If this is a requirement, then please raise an enhancement request through the ideas portal in the EngageOne Precisely community where it will be reviewed by product management and voted on by the wider community.
