Adding a "standard" marker when creating a new map?

[Andreas26188]

Hi,
I have some maps which starts with only one marker in the center, maybe I add some markers laters and maybe this is the only one.
I would love to have a checkbox when creating a map, and when checked, the component will create the first marker automatically with lat/lon copied from map properties.
For now, I have to enter them twice, or pan the OSM and look again.
Copying would be much easier. Is that possible?

Thanks!
Andy
