[RedZebra123H]

Description of the feature you're suggesting.

In this video, he goes over how to add walkie talkies to flipper zero:

I like the changes he made in the Sub GHZ app for walkie talkies which is shown here:

https://github.com/jamisonderek/flipperzero-firmware-walkietalkie/blob/jamisonderek/walkietalkie/walkie_talkie.md

But, here are the changes that I think will make the Sub GHZ bettter.

Change 1 - Walkie Talkie Preset:
Custom_preset_name: TLK1
Custom_preset_module: CC1101
Custom_preset_data: 02 0D 0B 06 08 32 07 04 14 00 13 02 12 04 11 83 10 A7 15 06 18 18 19 1F 1D 00 1C 00 1B 07 20 FB 22 10 21 56 00 00 C0 00 00 00 00 00 00 00

Change 2 - Change the frequency in the middle of a recording

Change 3 - Add walkie talkie frequencies
Frequency: 462559000
Frequency: 462579000
Frequency: 462598000
Frequency: 462639000
Frequency: 462658000
Frequency: 462678000
Frequency: 462708000

Change 4 (not related to walkie talkies) - Add a feature where you can type more digits when adding a new frequency.
Can you make a feature where you can type maybe up to 8 numbers when adding a frequency? For example, when adding the walkie talkie frequencies, they need to be more specific than 5 digits.

Thank you!
