Red warning banner sometimes insufficient

When processing payrolls, under current functionality sometimes a red warning banner is in place at vthe top of the screen for certain items such as employee under NMW (most common) or a pension action, an in correct NI table letter etc.

We have found that some NMW warnings when checked are not accurate, and so this creates a situation where sometimes the user ignores the red banner for certain companies rather than clicking into it - this creates a problem if another type of warning occurs for that same company.

It would be useful if we could have a pop-up in the same style as when there is a processing note that has to be cleared before a payroll can be finalised.

To stop this being annoying it would be useful if we could toggle the pop-up function per company, and further turn on or off the type of warnings that are alerted.
