The phrase "Could you please support" is correct and can be used in written English. You can use it when you are asking someone to offer their assistance, agreement, or backing for something. For example: "Could you please support my proposal to hire additional staff for the sales department?".
Could you please confirm the receipt of this email?
Could you please bring it back?" So hard to do.
Could you, please?
Could you please help me?
Could you please tell me more?
Could you please expand on that?
Could you please help your readers out.
Awesome tool! I started using it one year ago and I never had to look for another app
