Placeholders for all objects of a certain type

[Hakon]

At the moment I have the order to document the renovation with 360 degree panoramas for some buildings. For this purpose, I took panoramas on several levels of the building at different times. I would now like to create a skin with which you can select the date using buttons and the floor using other buttons. And markings of the respective panoramas should then appear in the floor plan that matches the floor. It seems to me that the easiest way to do this is to first set all markers to invisible when clicking a button and then switch the valid ones back to visible. Is there a placeholder or a command that can be used to switch ALL markers on a floor plan invisibly?

Hi,
Firstly I have moved this to the skins forum, the user-designed skins forum are for people to share their skins.
Have a look at this post: viewtopic.php?f=6&t=13649

thank you very much, that was very educational.
However, I saw the video about the nested cloner and used it for the skin.

Which brings me to a new question, which I put in a new thread for the sake of clarity.
