Manually Add and Connect Input Blocks to Block Properties
Like any action block you can manually add this block to the Wires canvas and connect it to another block, selecting the block property it should be connected to.
1. Add an 
Input block to the canvas. 3. Draw a connection from Input to the block with the property you want to have set by this input. 4. Choose the block property to assign this input parameter to.
As this example shows, properties may also be in a 'header' for the mashable information source or mashup.
