Using columns inside a custom block Panel Blueprint

I’ve made a custom block. Some text fields and an image field. In the Panel I’d like the text fields to display on the left and the image field to display on the right. Is this possible?

I’ve tried adding columns, main and sidebar inside the custom block, but it’s not working. (I can’t figure out where the code would go and I’m not even sure if this is possible)

title: News

fields:
	newsblock:
		type: blocks
		label: News
		pretty: true
		fieldsets:
			- type: newsarticle
				name: News article
				preview: fields
				wysiwyg: true
				columns:
					main:
						width: 1/2
						fields:
							news_article_heading:
								type: text
								label: Article heading
							news_article_date:
								type: date
								label: Article date
							news_article_text:
								type: writer
								label: Article text
					sidebar:
						width: 1/2
						fields:			
							news_article_image:
								type: files
								label: Article photo
								multiple: false
								layout: cards
								size: medium
								image:
									back: white

Here’s the custom block in the Panel.

I’m hoping there is a way to position the text fields on the left, with the image field on the right?

I can see that it’s possible to adjust the width of individual fields, but I’m wondering if it is possible to place fields into columns, main and sidebar – all within a custom block.

No, not possible. Only thing you can use is tabs.

Okay, thanks
