Allow the instructor to override his schedule (i.e. sick or management days)

As an instructor with a very random schedule, it takes me way too long to put in my next month time into Instructor Work Schedule, because of all the selecting of date/times one by one. Could you please make a spreadsheet type view entry and/or even better an excel based import entry. Columns would be: Schedule Type (On or Off) | Start Date | End Date | Start Time | End Time. So Something like:

Time Type Start Date End Date Start Time End Time
On 11/27/2021 11/27/2021 700 2200
On 11/28/2021 11/28/2021 800 2000
On 11/29/2021 11/29/2021 1200 2100
On 11/30/2021 11/30/2021 1400 2000
On 12/1/2021 12/1/2021 900 1700

If not the above then at least please optimize the current input process. There is SO MUCH you could do to make this simpler and faster... some suggestions: 1) having the End Date pre-fill based on the From date entry 2) the End time pre filled in based on the Start time. 3) maybe even pre-fill the start date to be plus 1 day from the prior entry.

I cannot determine what instructor is available
