You can program up to 7 blinks with the factory LCM and NCS Expert and NCS Dummy.
Basically, open up the LSZ.C36 (if 4.0) or LSZ.C37 (4.5) file with NCS Dummy without loading any FSW_PSW files, go down to cycle_ti_blk, right click it, and click "add parameter". Name it whatever you want, and under data put the number of blinks you want (maximum is 7). Then click on module -> update module.
You should be able to use that new parameter when coding the LSZ now.
