Phillip,
If I understand your question, you want to 'turn on' the recording upon receiving an "enable"
stream tag. I would look at the following blocks or maybe use a simple Embedded Python block:
Note: Mute outputs zeros when muted; the Selector outputs nothing when disabled.
Think outside the box.

Hello,
I am new to GNU Radio and am wondering question in the subject is possible.
In my application, I am transmitting a signal from a file source and
need to record sections of that signal at periodic intervals into a
file sink. However, I noticed that the E320 receives noise before the
desired signal begins transmitting and results in noise being recorded
at the beginning of the file. Is it possible to use a selector block to
switch the output to the file sink path after receiving some "enable"
stream tag in order not to record noise at the beginning?
Any alternative solutions would also be appreciated. Thank you in advance.
Regards,
Phillip
