Chat macro target (question)

[Sinrite]

I have Think Out Loud, and really appreciate it for spells and such that it supports.
I have edited my ToL macros to say what I want them to say with no issues, but when I tried to make a simple chat macro, it doesn't work out the same.

What I would like is a simple macro something like:
/say Targeting %F. Please focus my target.

I searched a few threads, but every one I looked at quickly devolved into something along the lines of people freaking out about botting or how macros were bannable...
Is a macro like this a possibility, or do we lack the functionality for something like this?
