Custom restore points

[sdt]

Is there a way I can set a custom restore point to my sessions ? 

eg: Iam running this dictionary combination on a large hash file of around 1.6M hashes

Code:

hashcat -m 124 -a 1 -O -w 3  -o all.found hashes.txt example.dict suffix.dict  --session ex1

And these are my running stats -

Code:

Progress.........: 1058334043200/5655470689344 (18.71%)                                                      
Rejected.........: 0/1058334043200 (0.00%)                                                                  
Restore.Point....: 0/128416 (0.00%)                                                                          
Restore.Sub.#1...: Salt:196224 Amplifier:0-42 Iteration:0-42 

Though it has gone around 19%, the restore points have not moved . Iam not sure about when the restore points get updated , but when I stop and start the session, it starts the iterations all over again . ( essentially wasting the runs  that were already done . )

The checkpoints option also does not work since they are never reached??? even the first checkpoint ?

1) Is there a way I can set a custom / manually create a checkpoint / restore point ? ( I checked the -s option - but that seems to be for skipping the number of words in the dictionary - might be suitable when Iam using only 1 dictionary ) 

Any clues on how to interpret the restore / checkpoints ? 
Thanks
