How to merge several paths into one in svg?

Question

JavaScript

Hello dear developers.
In the process of work, it became necessary to combine several paths into one. It is to merge, not group (g, use, etc.), for example:

<path d="m 648.6,575 c -0.5,0 -0.9,-0.4 -1,-0.9 -0.1 z" />
<path d="m 648.6,575 c -0.5,0 -0.71,-1.4 -1,-3.9 -0.4 z" />
<path d="m 548.4,575 c -1.5,0 -4.71,-1.4 -1,-3.9 -1.1 z" />

and it should turn out:

<path d="m 648.6,575 c -0.5,0 -0.9,-0.4 -1,-0.9 -0.1 648.6,575 c -0.5,0 -0.71,-1.4 -1,-3.9 -0.4 548.4,575 c -1.5,0 -4.71,-1.4 -1,-3.9 -1.1 z" />

Such a task arose when creating animation, because. when using multiple paths, the figure is drawn ugly than when using a single path.
I apologize if the question is stupid, because. I am not a designer.
Thank you very much in advance.

<path 
d="m 648.6,575 c -0.5,0 -0.9,-0.4 -1,-0.9 -0.1 z
m 648.6,575 c -0.5,0 -0.71,-1.4 -1,-3.9 -0.4 z
m 548.4,575 c -1.5,0 -4.71,-1.4 -1,-3.9 -1.1 z
"/>

Each M on a new line.
