Load Planning via Open Batch in 11.1.2.4

We are trying to load a Planning application via Open Batch process.  The default Export Mode is "Store Data" when you manually Export.

For example:  the filename is placed in the openbatch folder is "a~TestLocation~Actual~Jan-2016~RM.txt"

When loading HFM via Open Batch you have two Export options:  (M)Merge or (R)Replace.  There is no documentation in the Admin Guide specifically for file convention naming for loading Planning.  I'm wondering if you use "M" in the filename that equates to "Store Data" and "R" equates to "Replace Data" when loading Planning?  I would think they would have two options for Planning:  (S)Store Data and (R)Replace Data.
