Router OS 6.x Split upload and download in simple queue

Hi,
Is it possible to separate upload and download traffic in simple queues?
For example, we have a line of 50/50 Mbps
Now we want to make rules for upload and download traffic.
For example we use google drive.
Is it possible to make rules for limit upload traffic to google drive and also make ruls to limit download traffic from google drive?
Now I have configured Queue Tree but in version 6 there is no difference between upload or download traffic. So I look to rebuild the config and use simple queue.
Hope someone can give me the right answere and help.
Thanks a lot.

Nobody?
Come on people

Great,
Is there no one with this knowledge?

not sure how simple queues work, but in queue tree you can limit upload and download based on packet marks
you add marks to packets in firewall mangle, where you can tell the router to mark packets from your ip’s and other mark for packets to your ip’

Use target option, traffic that have src-address as target address will be automagically classified as upload and all traffic with dst-address as target address will be classified as download. Thats it.

Simple queues can’t function properly without target.

Thanks a lot for this reply. I was wainting for this a long time.
Can you also provide me with an example?
