Feature request: allow empty(null) values in RelativeRangeDatePicker presets #186
Description
Hello!
Currently, presets props of RelativeRangeDatePicker require both dates(start and end) and sometimes it's convenient to have periods with at least one open date(i.e. "starts from now" or "ends at now+30d").
Suggestion: allow null value in presets which will correspond to empty date in picker.
