Enforcing a data entry format on a Single Line Text Field

[ColinB]

Hi,

I was asked to add a couple of custom fields to allow the team to enter, a dev and test estimate using story points and have them appear on the backlog screen. This all worked fine using number fields.

There are stories that only require test effort (rightly or wrongly). As there are no labels to signify what the value refers to, and the display put the >0 test estimate first, if the dev was blank or 0. Visually one wouldn't know whether it referred to the dev estimate or the test estimate.

I got around this by making them text fields instead and entering a D in front of the Dev Estimate and T in front of the test estimate.

Now you see, for example. D5 T3, or None T8

The obvious problem here is people might forget to add the D or the T.

So from my dev days, prior to 'agile practice coach' I got to thinking about using some form of regular expression to enforce the first character to be D and the estimate number and T and the estimate number.

Is this possible?

Many thanks in advance for any suggestions and happy to clarify any ambiguity in the above.
