Combining files from two cameras in Lightroom?

I have a 5D3 and 6D I often use together for shoots. When I import photos from both cards into lightroom I have everything set to organize by capture time, but even with this selected my files always remain separated by capture time on each camera within the same folder (i.e. all the 5D3 files first then 6D files right after that).Is there a way to have these all combined together sorted by capture time? I have both camera clocks synced to the second. via /r/photography http://ift.tt/2udrERp
