part names in overlay for preset buttons should be different

[werwolfberlin]

for the most buttons there is the same part name "preset-button" so you cannot hide them with css. ideally the part name would be solmething like the following:

today-preset-button
yesterday-preset-button
.
.
.
cancel-preset-button

that way it is possible to use the contains operator ~= in the selector to select all preset-buttons and the distinct part name to select an individual button
