Picker Notes on hand held devices

We have a requirement to show the pickers,  using hand held device, certain notes/instructions related to customers (example, pick all the next tasks with export skids).
As of now the key challenge is that we are unable to use a note field in picking task screen in hand held units. There is a "to mobile picker" attachment but that is at the inventory item level and not for customer level.

Is there a way we can show the shipping instructions/packing instructions from sales order lines in hand held units?

Thanks!
