Adding wash during cycle

[master_mateusz]

Question for users of Samsung washing machines WITHOUT the AddWash function (WITHOUT an extra door):

- is it possible to add items during the washing cycle?
- Does this involve restarting the program (starting the washing from scratch)? If so, is there a reweighting (e.g., the washing machine has already started pumping water, I stop the program, open the door, add laundry, click start again - is there a reweighting here, with "wet" laundry - and thus the whole wash takes much longer than originally intended)?

For the sake of accuracy, I would appreciate the exact model of your washing machine when answering.

we have a WW90T534 washing machine without the little add was door. many a time if we have forgotten something we just press pause button on front of fascia and the door lock unclicks immediately and we just add the extra washing . 
Only time it does not let you do that is obviously if its a wash where the water level has come up past the rubber seal at the bottom of the glass door or if you are halfway through a wash cycle
