Multiline Caption not possible in Cloud version?

In Lightroom Classic CC the Caption field allows multiple lines. In Adobe Bridge you see this field as Description under IPTC Core. Similarly this appear as Description in Photoshop under File Info. In both Bridge and PhotoShop these fields are multiline.

But in Lightroom CC, desktop, mobile and web version, this field appear as single line only.

1. Is there a way to make this field multline in Lightroom CC?
2. If not - why is there inconsistency across the product line for this?

I had planned to be able to use my Laptop or Mobile to add information to family photos while out in the field. But the single-line restriction in Lightroom CC makes this impossible.
