Gap in a feature of size

[aniiben]

I have a faucet plastic component which has gaps/ interruptions along the circumference of an outside diameter. I cannot share the entire part, but something which is very similar is shown below. The outside diameter has 8 gaps around the 360° degrees which creates 8 arcs.
How can I define those 8 arcs related with a datum reference frame ?
I am using ASME 2009 (or with a note I can use 2018). I know I can use profile and position, but my question is:
Can I use CF- continuous feature per 2009 or 2018 with position ?
Can I use 8X size (.500±.015) and position?
(Profile and phantom circle is not much liked in my general industry- hence I will leave it to the last resort )

Burunduk,

By the way, fig. 8-24/2009 has profile and location control clearly defined. If you add CF to this scheme why it's not good enough and what is detrimental to the part definition?
Why this scheme cannot be used and we have to invent a new one?
Well, lack of education shall not be a reason, right?
Just asking loudly.........

greenimi,
8-24/2009 is an irregular feature of size that has position applied to at MMC. The possible design intent for something similar is to ensure clearance to a mating component that should fit with a gap in the semi-rectangular opening, while relaxing the requirement as the opening gets larger. I am not sure that this is similar enough to OP's design intent. I don't know OP's design intent. That's why I said "if the best choice functionally is plus and minus size and a tolerance of position, I would place the CF symbol near the size dimension."
