Bridge Infill Removal In modifiers

Does anyone know how to remove bridging infill from a part using a modifier? Modifier setting in picture. I'm making a lid for my swatch container and I want to label it using infill patern so I don't have to emboss or engrave it into the bottom leading to supports? I just want to remove it from the lettering not the whole thing. Iv tried fixing with netfab and nothing, changing infill angle to 180 but iv had zero luck. .3mf file here Swatch lid

RE:

Try the attached project.  

The problem is that if you have ANY top layers at all you will get bridge infill.  So the trick is to have zero top layers.  Of course this leaves you with no surface there.  So you set up a height range modifier and set the infill type to rectilinear and 100%.  This in effect gives you several flat 'top' layers.  Its infill but its still flat layers.

The other thing to then watch out for is your text modifiers.  As they are already set override the default infill 10% to 25% they will also act on the rectilinear infill, dropping that to 25% too which presumably you don't want.  So the idea is to make the text modifiers not as high and drop them to the bed so they don't interfere.  Which is what I did with one of them but left the other all the way through so you can see the effect.

Dallas-Cowboys-Layerheight jt    this is a test file added by Joan for fault finding purposes.
78b048cd-dallas-cowboys-layerheight-jt  same file above after adding to forum, then re adding using the add media option. 
But file doesn't seem to attach, using the Attach file option. 
 78b048cd-dallas-cowboys-layerheight-jt.zip prusa forum, seems to add a space in front of the file name, and consider it to be an XML file. 
Odd behaviour.

RE:

Sorry Brody, I appear to be having an issue with the file attachment process.  Since the forum was updated a couple of weeks ago everything I attach seems to produce an error on attempting to download it.  I did the example project on my work pc so tomorrow when Im back at work I will be sending it to Joan and get it attached for you.   

Hopefully Joan can sort out whats causing the issue.
