UEI made aftermarket universal remotes would give you access to numerical pad with use of advanced code or efc's. Which are 5-digit codes for individual functions. But sadly, it only works on Roku CH live channels or an antenna on Roku tv's. It would not work with Spectrum or Pluto apps. In the case of Roku tv's all you need is tv code 14398 or 4398 and the number pad is preset. With Ultra you would need to map each digit via 5-digit code, but only once per digit. The efc's are:
0- 00101
1- 00230
2- 00232
3- 00228
4- 00235
5- 00231
6- 00233
7- 00100
8- 00106
9- 00102
Ch UP- 00183
Ch Down- 00185
To map them to key on UEI made remote with setup code 03061 or 3061:
1. stream device
2. press and hold SETUP for two blinks, release
3. enter 9 9 4
4. tap SETUP for one blink
5. enter 5-digit code
6. pick a key
continue for each numeral but using a different 5-digit code in step five and picking a different key in step six.
An example of UEI universal remote is the Inteset 4:
