Show % formatted items description as a % rather than just showing description as 'Number'

If I format a line item or property as a % it is only shown in the blueprint or grid view as 'Number'. It is not easily identifiable as a % wotjout going into the line item and checking the % option has been ticked and the number of decimla places. Could we have this shown as a format description as 'number% 2dp' for example to highlight to admin that it has been set up as a % correctly and with in this case 2 decimal places. 

Also like the idea of setting up a default % format which can then be applied to all % items rather than having to set up each item individually.

Thanks
