Remove stars above 3rd magnitude from CdC or Stellarium - any suggestions?

[Gfamily]

It's not generally known that the GAIA satellite has problems with getting data for stars brighter than 3rd magnitude. For these, the image 'bleeds' which means that the stars' data needs to be subjected to specific data processing to be able to get data at the same level of precision as for other stars*. 

I would like to put together a modified sky map, to show what our sky looks like without the brightest 230 stars - but I'm not sure whether it's possible to take the 'standard' catalog for either of these two programs and edit it to remove the brightest stars. 

Does anyone have any suggestions on how to do this? 

* We're fortunate in fact, before commissioning, it was thought that GAIA would be limited to getting astrometric data for stars brighter than 5.7 - which would exclude practically all stars visible to the naked eye.

The solution (for Cartes du Ciel at least) is to use the Setup | Catalog... | Catgen utility. 

I can download the Bright Star Catalog (9110 stars) from CDS

Import into Excel and remove rows that are brighter than Mag 3 

Save as a text file and use Catgen to create a binary indexed file. Use this file as the only Catalog for CduC and all the familiar star patterns disappear
