EV-ADF4360-7EB1Z gerber file

I want to  transfer gerber file of EV-ADF4360-7EB1Z to pcb file in altium designer ,and I want to know if ADI could provide specific description of layer. for example, when I import the gerber file ,the layer sm0428 smd004022 smd004022 were defined MASK bot layer by default,and I think it is difficult to define layer in AD,so could ADI give the layer type in gerber file?
