How to replicate only part of a texture?

Question

WebGL

I have an image which I use as a texture.



And I want to repeat only part of this texture. For example, the third rectangle in the first row is from [0.5,0] to [0.75, 0.25]. (brown)

Is there a way to do this in Webgl 2?

ps. maybe it can be done with textureOffset and something else...

I would be very grateful for the information in this thread!
