When adding markers, it would be practical to have an option which when enabled allows user to click portals one by one to add the selected marker type.
Suggestion :
In the "Add marker" popup, add a checkbox to enable the mode.
When enabled, the selected marker type is added each time a portal is selected with the associated parameters.
I've been thinking through something along those lines as well. I find myself placing many markers of the same type at once. I have no suggestions, just voicing support for exploring the idea.
