is there a way to convert potassium perchlorate into chlorate?

i would like to know if there is a way to convert or decompose potassium perchlorate (KClO4)
into chlorate (KClO3), because currently i require some chlorate, and all i can get is perchlorate.

i require it for a chemical reaction which will begin at 300C instead of 600C
for what i require it for, i need it as a chlorate, not perchlorate.

also, its impossible to search my question because all results say how to turn chlorate to perchlorate, and not the other way around

Oh dear I wonder why you want to do such a thing!!!

Sorry as a responsible adult I find myself unable to reply.

If you can't understand other stuff you can get from the WW I am not going to help.
