Can I have different breakpoints for the same table data on a 1-D lookup table in Simulink?

Ideally I would like to have a lookup table that the table data remain the same while the breakpoints can be multiplied by an external 'x' value. For example, if I have [1 2 3 4] as table data and [1 2 3 4] as breakpoints, I want to have [1*x 2*x 3*x 4*x] as breakpoints, where I will set the x value in each case. I know that I can do something like x*[...] on the breakpoints but I was thinking if it is possible to do it like a mask block.
