Tried this on our Prius+  , since the front seat heather button is hard to see and operate from driver seat . (as in Toyota Yaris, where the seat heat button is placed underneath the hand brake and hard to see from drivers site) Attatched an self adhesive halfround pearl (one of those scrapbook ish) to each heath control button. Perhaps need some superglue for more permanent use. Works fine imo. Easier to find/feel and operate.
