quick add start dates/due dates entered by actual dates

[jrgreensboro]

Is your feature request related to a problem? Please describe.
quick add only allows dates by offset - 1D, 2D etc etc.

In the original taskunifer you could enter an actual start date with ">MM/DD/YYYY" and due date with "<mm/DD/YYYY"

a similar scheme for quick add would be invaluable rather than be constrained to offset days. For example i know i have a bill due 12/27/2020 -- i need to e able to quickly enter that date -- an offset date doesn't help -- i then have to find the task after entered and update the date manually which negates the purpose of "quick add" bar

the offset dates are great and shoudl be kept, but a way of entering an actual date would be invaluable and would be consistent of the behavior of original TU.

thanks
