Setting constant input layer in QGIS modeler?

Question

I have a model in QGIS where there are two vector layers that remain the same everytime I execute a model.

Is there a way that I can configure my model so that these layers don't require the user to "input" them. Ideally I could point to their location in my model file and not need the user to even know about them. Maybe you can do this already but I can't find the tool I need in the processing toolbox.

Quite a late answer but instead of using a Vector layer input in your modeler, you can instead create two custom scripts and add the paths of your layers into each script. To create such a script, go to:

Processing Toolbox > Scripts > Tools > Create new script

Then use similar code below.

First script:

##layer_1=name
##output=output vector
output = "C:/Users/You/Desktop/layer_1.shp"

Second script:

##layer_2=name
##output=output vector
output = "C:/Users/You/Desktop/layer_2.shp"

Make sure the scripts are saved in:

/.qgis2/processing/scripts/

If you run the scripts individually, they will simply load the layer into the interface.

Then add them to your model:
