How to combine non-interleaved mono-files in S1?

is there a way to tell S1 when importing tracks to combine non-interleaved mono-files to a stereo-file? I have some multitracks with files like this: OH.L, OH.R, Pad.L, Pad.R. These could be combined to stereo, but I don't see how to do it.

Logic X just combines these files as default on importing. If I don't want them to get combined I have to rename them to something different like : OH.L1 OH.R1. That's a good solution.

Or is there a way in S1 that I'm not seeing?

Thanks,
