Can exchanges bundle withdrawals?

Just a quick question. I’m curious if anyone knows if exchanges can bundle withdrawal’s made by individuals?

For example, I use an exchange called Shakepay in Canada and they don’t charge for withdrawing your crypto to a wallet. So would the exchange potentially wait until 10 or 20 people withdrawal their crypto before submitting the request to the blockchain? Is this even possible to for the exchange to do this to save them for paying for gas fees for each of their retail investor withdrawals?

Thanks!
