Can the end user type in numbers?

I am makeing a capacity report which shows how many tasks we can take in each month and how much capacity we have.

The number of tasks are calculated automatically, but the capacity is typed in manueal.

The way I have done it so far is simply to add a new table with the numbers from 0 to 250 like this 

Capacity:_table = GENERATESERIES(0,250,1)

Than I have made a filter where the end user can set the minimum number and than I use this Dax in the relevant formles

Capacity_value = MIN(Kapacitet[Value])

I just don't feel like this is a paticular elegant solution. One of the problem is that my filter show both the minimum and maximum value even though I only need the minimum value.
Another problem is that she cannot type in any numbers higher than the maximum value I choose.

So I just want to ask if their is a better way to solve my problem with allowing the end user to type in numbers?

Thanks for the answer.
A single selected dropdown will be pretty intimidating if it includes all numbers from 0 to a 1000.
I will just go with the solution I have so far, but it was nice to figure out that their isn't a better alternative out there.

You could change your slicer to a single select dropdown instead of a range slicer and extend your generated range but there's not a clean way to accept user input other than the What-If Parameter method you're already doing unless you go the way of a PowerApps custom visual.
