[MapProxy] seed only a section from wmts server

[Dwayne Dibbley]

I have a config to pull from this wtms server:

https://wmts.maptiler.com/aHR0cHM6Ly9ubHMudGlsZXNlcnZlci5jb20vZnBzVVpieHRndGtuL2luZGV4Lmpzb24/wmts

here the config:

services:
  demo:
  wms:
    md:
      title: OS 10k 1888
layers:
  - name: osgb10k1888
    title: OS 10k 1888
    sources: [osgb10k1888_cache]
caches:
  osgb10k1888_cache:
    sources: [osgb10k1888_wmts]
grids: [nls_grid]
sources:
  osgb10k1888_wmts:
    type: tile
grid: nls_grid
    url: https://nls-0.tileserver.com/fpsUZbxtgtkn/%(z)s/%(x)s/%(y)s.jpg
grids:
  nls_grid:
    origin: nw
srs: 'EPSG:4326'
    bbox: [-7.793077, 49.852539, 1.790425, 60.894042]
bbox_srs: EPSG:4326

How would I go about only seeding a small area instead of the complete area?

Many Thanks
