I'm using WLP v. 6.3.14.0. I run 10 different strategies on 2 different watch lists for a total of 20 entries in my strategy monitor. Before opening the strategy monitor, I enter the scale (Daily) and data range in the left panel and use Data Manager to update the data through the current date. Upon completion, I open the Strategy Monitor. The data range remains the same as the previous day that I ran the strategies. In attempting to change the data range using "Change Settings", the end date for the data range is grayed out so that it cannot be changed. The only solution I have found is to remove every strategy from the monitor and add it back again. Then I can set the data range to include the current day. Is there a less time-consuming way to accomplish this task?

First, let me note that one should not choose a End Date when selecting a data range in the Strategy Monitor. There's a live bug: the option should be ignored by the SM but it's not. Consequently, to select a proper Date Range one needs to enter a distant future end date. The easier alternative is to select either 'Fixed Bars' or 'Most Recent'. If the end date is grayed out, it's expected, and it means that you've selected one of the "right" options.

What you're doing does not seem to make sense to me. If you need to execute a Strategy right now, right click on it in the SM and choose "Run this Strategy Now". (There's no need to update the data manually, as the SM will do that itself). Otherwise, just leave it running - until the projected "Next Run Date".
