How to send the same pwm signal my board just read?

so working on a project where i am reading the PWM signal coming from and RC receiver, as I read the

signal id like to pass it along but, retain the ability to inject my own signal as needed is this possible?

I can read the signal just fine, but did not know how to make my ardunio pass the intact value, and

resend the same signal it just received

With the Servo library?

so i cant simply read the signal and then output the identical signal? i have to take it, munch it up, map it and output it as a servo angle?

seems abit convoluted when i already know what my signal needs to look like,

Why map it to an angle?
Presumably, you know the length of the pulse in microseconds..
