How to choose which address the E-Mail notifications will go to when placing an order in opencart 2.3.0.2?

Question

opencart

The essence of the task is as follows, when paying for an order, it is necessary to make a choice of the address where the order will be prepared (approximately as in Figure 1, but it can also be done in separate blocks, there are only 2 addresses). The main point is that we have 2 mailboxes and, depending on the address, the letter will be sent to a specific mailbox.
Those. (I understand it may sound confusing)
1 address - the letter arrives at the 1st mailbox
2nd address - the letter arrives at the 2nd mailbox
. And so I ask for help, maybe there are some modules, infa., Or maybe direct me on the right path. I thought somehow the problem was through "Additional notification addresses" (2 figs), but I don't know if I'm thinking correctly.
