Different Encode and Decode PL Tones on Repeaters

We are seeing repeaters adopting separate PL codes for Encode and Decode as in the example below - Is there any plans for Flex to add support for independent tones?

    perhaps you could have the radio in split mode, instead of repeater mode, set transmit pl in one slice, then set ctcss in receive slice

    n 50 years on FM I don't think I have owned an HT or mobile rig that could do that.

    A number of newer radios allow a different tone to be entered for receive... Beofangs as an example. Unfortunately there are repeater ops who are starting to adopt different input/output tones. It's a minor inconvenience not to have, but it would be nice.

    I get that different I/O tones can be set, but why would a repeater operator ever do that?

    In my repeater day's i used different pl's on the repeater output to link to some other repeaters linked system, i even used dpl (digital pl) on some cases. Sometimes its also used to keep jammers out, they decode the output pl and unless they know the input pl they won't be able to key the repeater so they are being fooled. So there is various reasons why  these are just some.

    Could you name a Yaesu, Icom or Kenwood model that provides different output and input PL tones?

    Most if not all the commercial radios (not ham) out of the big three manufacturers will let you program different pl's for input and out. Lets go back to the Flex radio now.

    PAPA repeater system in SoCal is extensive and are moving to split frequencies. The repeater handbook as shown in the original post clearly lists repeaters that have already adopted split frequencies. It’s happening irrespective of how you feel about it or what radios don’t have it. It’s a simple software tweak to support it.

    Kenwood D710, D72, and D74 all support it ("Cross Tone" mode "T/C"). Several Yaesus (FTM-350, FTM-400, VX-7 at least) also support it, but they don't seem to have a way to front-panel program it; you have to PC-program a channel to get different RX and TX tones.
