Custom shapes in editor

I love PDF24 as a free replacement to Adobe Acrobat, however there are some shortcomings;

Specifically, I would like to be able to easily add custom shapes (stamps) and objects to the Edit/Annotation tool(s), but as far as I've found so far, this is not currently possible. As examples, symbols like ❌, ✅, ❔ and predefined "sign here" or "account:" stamp-like shapes would be great to easily apply.

As far as the unicode symbols I used as examples above, yes; I could just use a textbox and add those, but it is inconvenient when several need to be added.

Is there any hope to see something like this in the near future? Also; I am focused on the on-prem tool, not the online version, but I feel this could benefit both versions.

Thank you for reading and considering!
