Creating adaptive tag icons

[rowan.sluisQ7HV5]

Hello.

I am trying to create a tag that shows in what layer my rebar is place. I'd like to have this show as an icon. A little flag in this case. I know how to make labels in tags and that i can connect parameters to these labels to show their value. But is it also possible to make icons that change depending on de value.

If i put my rebar in the 4th layer i'd like to have 4 vlags attached to it (see, image below). 

I have created this using parameters in de tag itself. I made a parameter in de tag that says "RebarLayer" -> value: "4" (see image 2 below). The problem is that i would have to manually put these values in each of my rebar tags. I want to only put it on the rebar element parameters. 

Anyone knows a way to get this done?

add another parameter depending on if condition i think it might work

The problem is I have only been able to add if conditions to the parameters of the tag itself and not from the element its attached to. Only the Label function has this feature.
