Designing a filter from magnitude response plot

Hello everyone,
I'm supposed to replicate a series of analog filters as faitfhully as possible in Matlab. I've been given a plot of the filters magnitude response (no phase plot):
![response.png](https://www.mathworks.com/matlabcentral/answers/uploaded_files/194855/response.png)
Yes, theres a gain stage too, I can just amplify the signal at the end.
I want to replicate the red trace (I also have the values used to construct the plot in an EXCEL table with the frequencues and their corresponding gains).
QUESTION: Is there a way in Matlab to take the columns of this frequency and gain table and create a set of filters on Matlag that would give me an identical response? Unfortunately thats all I know about the original filters :/. I do realize the phase response might be different but apparently it doesnt matter?
Thank you!
RC
