How to import only RAW files from camera?

Question

I also shoot with both RAW and JPEG, such that I have access to JPEGs to share with people immediately before post-processing.  But I only want to use RAW in my Lightroom flow.
When pictures are already in Lightroom, I use filters in the library view to show only RAW, or only JPEG, or both (by applying a filter on the file extension).
But how do I set a filter before importing?  I would like to import only the RAW pictures into lightroom, but I don't see a way of doing that using Lightroom's import from camera card features.  I either have to let lightroom  import all, and then remove the JPEGs, or use Windows explorer to copy over just RAW files and then use Lightroom to import.
I would like to use Lightroom in just one step to import all RAW files (but only RAW files) from the camera card directly to the library.  A file filter in the import dialog seems like an easy feature to implement.

Another reason to have a filter in import is then you can then apply a preset to the RAW files only. At present if I want to apply a preset to my RAW files on import I have to apply it to the JPEGs too as there is no way of being selective on import. I then have to remove the preset from the JPEGs, which is a pointless and unnecessary task, whilst LR is busy rendering the unwanted look.
I shoot both file types on one cameras as the JPEG gives me a look that is very hard to replicate with the RAW files and on another camera I use a picture style to remind me of what I was looking for when shooting. Again as it's a custom style it's very hard to replicate the look in LR from the RAW file.
Though a major reason I shoot both JPEGs + RAW is that I was asked by a client a few years back, when I only shot RAW for all the shots as JPEGs to select down from. As this was a 4 week feature film shoot it took several days constant rendering out of Photoshop to output the JPEGs. This was just before LR and even then, LR would still take considerable time to produce all those exported files, though a lot quicker than PS I would hope. So now I always shoot JPEGs as well so I never have to waste time outputting JPEGs for a client to do a rough select.
