Bittorent Sync - is it possible to sync only for writing?

Question

bittorrent

Good afternoon dear experts. There are 3 computers. 2 of them are "working", i.e. certain folders on these computers store files that need to be accessed from anywhere. The third is a personal laptop, i.e. on it, in addition to the specified files, personal documents can also be stored.
Q: Is it possible to set up "write only" synchronization on a personal laptop? Those. the first 2 computers must be synchronized with each other. And the laptop should download the files changed on the first two computers. But files from a laptop should not go to the first computer. As I understand it, Read Only is not exactly what I need, because I don't want btsync to transfer files from laptop somewhere. And I don't mind if new files are downloaded to the laptop from the first two computers.
