When I add tylose to MMF do I have to add it when I make a batch?

I have some leftover MMF from a cake this weekend and was hoping I could just knead it into it. Will that work?

i did this once... i add the tylose when i was melting the marshmallows... the result? it has bumps all over it... i tried to knead it longer but still it doesnt go away... try to add it on your powder sugar... to save your energy and time. trust me

if youre going to add it to your leftover MMF, just mix tylose with the powder sugar and knead it in. that will do.

thanks!!
