P6, Resource Assignment would not import for repeated resource

I try to import Resource Assignment from Excel to P6, 

I have several activities that have repeated resource. When I import the excel file to update my P6 project, only the first resource iis imported while other repeated resource will be ignore. Is there any method to make P6 import all repeated resources without ignoring the repeated resource?

I cannot create the repeated resource as a new resource because I need the collect the repeated resources data later as one lumpsump data.
