Symbol Names in ParsedFunction

[TLWise]

I am having to define functions similar to the one below for a large number of objects. I would like to define the constants used in this case as symbol_names as global parameters that do not have to be defined each and every time as in the below example. Is there a way to reduce the repitetion of constant value definition for each function that will have to be defined?

  [./p14displ_x]
    type = ParsedFunction 
    symbol_names = 'A P02 tau2 m xf zf yf xi_1 xi_2 Vmax t0 n'    
    symbol_values = '7.85e-7 1e6 2.0e-3 2.0e-6 4.77e-3 0.0 0.0 1.53e5 6.375e6 392.5 8.0e-4 2'           
    expression = 'if(t < t0*n, 1e-1*t+x, (A*P02*tau2/m*(1-exp(-(t0*n)/tau2))/xi_1*(1-exp(-xi_1*t))/Vmax)+x)'# x+(A*P02*tau2/m*(1-exp(-t/tau2)))*sin(cot((yf-y)/(xf-x))) #(A*P02*tau2/m*(1-exp(-t/tau2)))*sin(cot((yf-y)/(xf-x))))

At the top of your input file (not within any block), you can define the parameter

param = 0

and then access it anywhere within any block with ${param}

yes that is correct. So something like:

A = 7.85e-7
P02 = 1e6
....
