Multi-line custom property field?

[itsme213]

Is it possible to add a multi-line custom property field?

I would like to add "documentation" fields to shapes that represent software objects (like classes, packages, etc.)

I would like the user to be able to enter multiple lines of text into these fields.

When I select a "String" custom property I just get a single text field, suitable for a something like a short name string.

Thanks!
