Can I modify presets' values (e.g. amplitudes)?

[yyphan]

Hi I have been trying to get customized vibrations on my Android phone (the blame is on its hardware), so far the only thing that worked was HapticPatterns.PlayPreset(). Then when I look at the source code I realized the presets seemed to be defined using amplitudes and time, too. I wonder if I could modified the presets' values to make them 'customizable'.

I did a few attempts without avail but just wondering if it makes sense at all. Thank you for your time
