DHT-22 Sensor wiring with a twist

Projects General Guidance
1

Hello,
I have a portable breadboard that has several components that attach to DHT-22 (AM2302) wired sensors located in different places that have integrated resistors for pullup/pulldown. (see picture below)

I just recently begun to start using the DHT-22 version that has no integrated resistor built in. Since i move the breadboard often enough, i don't like to have to rewire it for each sensor type. What i would like to do is wire the breadboard for both both scenarios so that it is set up like 2 "ports". I don't mind a bit of redundancy in the wiring to get two separate locations on the breadboard to make separate "ports"

Port 1, would be the existing wiring as shown in the picture (DHT-22 with integrated resistor).
Port 2, would be located and attached in the green box with no integrated resistor in the sensor.

The whole point of the exercise, is that i don't make a mistake in forgetting to rewire it. I have read adafruit's instructions on how to wire the "port 2" version, but i am concerned that wiring exactly the same way will interfere with port 1 functionality.

How would Adafruit's instructions be changed to allow for both ports.

Thanks

According to Adafruit's web site using an additional external pull-up is OK even when one is built in. Wire a 10k pull-up and use the same "port" for all.

Cool.
I have seen different documentation quote 10k resistors, but some are supplied with 4.7k. If i am to use an additional resistor, (2) in total, am i better of using a 4.7k or a 10k or does it not matter

Thanks

10k would be the best, it works well on its own and would give a rough equivalent to a 4k7 if the device has 10k built in.
