Feature request: markdown/template in section header

[BBE-FR]

It would be a marvelous capability to be able to use template or markdown in the header card that is available in section mode.

This card is curently capable to display icon / name and entities.

It is a very convenient card.

If a template / markdown part was available to allow to display some dynamic information, that would be marvelous, preferably in the place of the "name".

Of course it is possible to use a dedicated helper for this, but only at the end of the section, not in the name space.
