You mean a press and hold button style in the UI? You can’t do that in BasicUI, not sure about HABpanel.
You can make a press-on , press-off button.

Have you checked out the profile feature to define your time as a rawbutton-toggle-switch: https://www.openhab.org/docs/configuration/items.html#profiles
thi may provide the feature you are looking for.
