A shame we can't have automatic "Thanks for healing" voice lines besides Rakan/Xayah

Whenever you heal an ally in HotS, you usually hear a voice line that more-or-less is a "thank you for the healing" line. It's a small touch that helps support players feel good about doing their job.

This would've been great to have in League, but presently the only one who does it is Xayah, and only if healed by Rakan. I'm guessing it'd be too much work now, but in hindsight Riot should've considered it in the first place.

Maybe an automated Emote could serve as a small substitute (with the option for the player to turn on/off said automated emotes).
