Signal Providers Lot Size Question

Hi guys, I'm fairly new to Forex and only started following a signal provider today! Quick question...I understand the ratio used to work out the Lot Size between provider and subscriber but I was wondering; if my account balance is larger than my signal providers would I be able to trade a Lot Size greater than theres?

i.e. At the moment if they trade 1.0 and I am 0.85, if I doubled my account balance deposit could I trade a Lot Size of 1.70 while my provider is still trading 1?

Thanks
