Add prefix and suffix to the OTP Code when inserting

[d4rpx1]

Hi!

I've come across are some Requests that require an OTP which does not have a default value, for example a post request with the body username=user&otp=&password=pw.

It would be a nice feature a prefix/suffix could be added to the inserted code, this way you could use otp= as the expression to match and add otp= as the prefix to the code, so otp= would be replaced with otp=000000 (valid OTP code)

This is a good idea — open to a PR.
