Currently the response speed is one timing, which may not be suitable or realistic as some replies are longer than others.
Having the following options would be helpful:
  1. Enter a range of timings you are happy with i.e. 15 - 45 seconds
  2. Have a response time based on reply length i.e. if the reply is 'yes we do' then 45 secs is not ideal, likewise if the response is 30 words long, 15 secs is too short as it highlights a bot is being used.
  3. Have a random timing within your range i.e. It might be 20 secs for first reply, 45 for 2nd, 31 for 3rd and so on....
  4. The ability for the first reply being set and subsequent replies being random so that the first message is answered quickly.
