I have a tutorial on how to write a bit of pyqgis code to do this that shows exactly the use case you have. But it can be used with any other processing algorithm. https://www.qgistutorials.com/en/docs/3/processing_algorithms_pyqgis.html [Image removed by sender.

I have been asked to sample over 100 raster pixel values using a single point file. I can use the “Sample raster values” Tool, but this only outputs for one Raster. I have looked at batching this, but it will produce 100’s of point files which I will have to merge together. So I was looking at using the Model Designer, but again it can’t accept multiple raster inputs. What I would like to know, is how I might easily create a single shapefile with a column for each raster containing the sampled value. The easiest way would be to somehow sample the first raster saving the output then loop back to the second raster, but this time using output from the first sampling to sample the second. This looping would continue until all raster’s had been sampled. Any help appreciated.
