Placing markers on PDF drawings

I would like the option to add markers directly in Gripr, as sometimes homes or locations do not have addresses.

I would like to be able to set the geolocation (marker) manually, directly on the map where I enter the address. In other words, instead of entering the address, I would also like to be able to set the marker where we want to go "manually," without having to enter the street name.

I am aware that I can upload the image. But then the location does not automatically appear on the map on, for example, my phone...
