Pick days, hours, and minutes for time limit

Is your feature request related to a problem? Please describe.
Currently, there is only one field to input the time limit. Assuming this field allows a numerical input for minutes, it's a bit inconvenient for the client to add longer games.

Describe the solution you'd like
There should be three fields, where the user puts in their desired days, hours, and minutes for time limit. (We should probably cap the days somewhere.) The front or backend should then calculate the days and hours into minutes and add that to the corresponding game's timeLimit field.
